Just wanting more information on the Extension - we are planning on upgrading from 10.2 to 10.3 and on all the release notes, blogs, websites all it pretty much says is that the GeoEvent Processor is now called GeoEvent Extension. So I have one main question (and haven't heard back from my ESRI Rep yet)
How much extra, on average, does the extension cost?
Any more advice or info on the Extension is welcomed 
Thanks!
